Experience Accuracy! Cell Counting & Analyzing with Arthur.


Arthur™, Image based cell analyzer is
3-channel (bright field, green fluorescence, red fluorescence) desktop image analyzer that allows users to perform assays for cells in suspension, including GFP and RFP expression, apoptosis, cell viability (live, dead, and total cells), cell cycle, and cell counting assays using state-of-the-art optics. lt is compatible with a wide variety of eukaryotic cells. Depending on complexity of the assay and number of fields captured, it takes 10 seconds to 2 minutes that Arthur™ counts for a typical assay with only 25 µL of sample volume.
